摘要
Method and apparatus for the spectroscopic analysis of a specimen in which the specimen is irradiated with a narrow band of monochromatic light over a range of wavelengths, the light reflected from the specimen is scanned to generate a signal representative thereof, the signal is converted into a digital signal and stored. Digital data representative of selected spectroscopic characteristics is also stored and the digital data and the spectroscopic data are read out to identify the spectroscopic characteristics of the specimen. A TV camera scanner enables selective gating by varying the respective horizontal and vertical portions of the video signal. The video signal may be visually monitored to alter the scanning of the specimen and to determine those portions of the signal to be gated.
